Betoniteräkset

Betoniteräkset, often translated as "concrete steel" or "reinforcing steel," refers to steel bars, also known as rebar, used to strengthen concrete. Concrete is strong in compression but weak in tension. Steel, on the other hand, has high tensile strength. By embedding steel reinforcing bars within concrete, the composite material, known as reinforced concrete, can withstand both compressive and tensile forces effectively. This combination makes reinforced concrete a fundamental building material in modern construction.

The use of betoniteräkset is widespread in various structures, including buildings, bridges, dams, and roads. The steel bars come in different diameters and grades, chosen based on the specific load requirements of the structure. They are typically arranged in a grid pattern and held in place with ties before concrete is poured. The surface of betoniteräkset is often ribbed or deformed to ensure a strong bond with the surrounding concrete, preventing slippage. Corrosion of the steel is a concern, and measures such as concrete cover, coatings, or stainless steel rebar are employed to protect it. The development and widespread application of betoniteräkset have revolutionized construction by enabling the creation of larger, more complex, and durable structures.
